Composite flame retardant to impart excellent flame retardancy and flame retardant resin composition comprising the same

摘要

The present invention relates to a composite flame retardant imparting excellent flame retardancy, which is compounded by adsorbing an organic flame retardant on the surface of the inorganic flame retardant, and a flame retardant resin composition comprising the same, wherein the composite flame retardant is an organic flame retardant adsorbed on the surface of the inorganic flame retardant Since it is complexed, it is possible to increase resin compatibility, and accordingly, the resin dispersibility is improved compared to inorganic flame retardants, and inorganic flame retardants, especially expanded graphite having poor resin dispersibility, can be added in a high content. Through this, it is possible to provide excellent flame retardancy in a wide range of UL94 V2 to V0. In particular, the flame-retardant resin composition comprising the composite flame retardant according to the present invention has the advantage that it can obtain a flame retardant effect of V1 or more without an antimony auxiliary flame retardant, and even contains a small amount of the flame retardant auxiliary agent through a high synergistic effect between the flame retardants. There is a characteristic that can give high flammability to
